A contactless dc electric motor comprises an electromechanical transducer which comprises an inductor on a movable portion and a first armature winding on the fixed portion which is connected to a first semiconductor power commutation switch connecting to a first discrete sensor of position of the movable portion relative to first armature winding. It also comprises a complimentary second armature winding connecting to second semiconductor power commutation switch which is connected to a second discrete sensor of movable portion position relative to the second armature winding, the second armature winding is shifted against first to a half of output signal of the sencor of the movable portion position. |
